2. x=buku
y=bollpoint
4x+5y=24.000*(3) 12x+15y=72.000
6x+2Y=27.000*(2) 12x+4y=54.000 -
11y=18.000
18.000/11=1636*2=3272( duabollpoint)
6x+2(1636)=27.000
6x+3272=27.000
6x=27.000-3272
6x=23728
23728/6=3945*2=7909(dua buku)
x = 61 - y x = 13 + y
13 + y = 61 - y = 13 + 24
2y = 48 = 37
y = 24
jadi bil. tersebut 24 dan 37

4x + 5y = 24.000 x6 24x + 30y =144.000
6x + 2y = 27.000 x4 24x +8y = 108.000 dikurangi
22y = 36.000
y = 36.000/22 = 1636,4
4x + 5y = 24.000
4x + 5(1636,4) = 24.000
4x + 8182 = 24.000
4x = 15.818
x = 3954,5
2(1636,4) + 2 (3954,5) = 3272,8 + 7909 = 11.181,8
